Abstract
The utility model relates to a lithium cell case for electric motor car has solved the problem that current lithium cell case accuse temperature and ventilation effect are poor, the structure is complicated. The technical scheme includes that the box cover comprises a box cover and a box body used for placing the lithium battery, wherein a ventilation opening is formed in one side of the box body, and an exhaust fan is installed on the other side of the box body. The utility model discloses simple structure, have advantages such as air exhaust, automatic temperature control.
Description
Technical field
The utility model relates to a kind of vehicle-mounted accumulator box, a kind of specifically electric vehicle lithium battery case.
Background technology
Electric motor car adopts lithium battery power supply usually; In order to guarantee Electrical Safety; The polylith lithium battery of these series connection need place battery case; During operation, need overcome lithium battery self work heating and environmental problem, therefore requiring battery case is being that lithium battery provides better condition aspect temperature, environment, stable, the ventilation.
Summary of the invention
The purpose of the utility model is in order to solve the problems of the technologies described above, and a kind of simple in structure, electric vehicle lithium battery case with air draft, advantage such as temperature automatically controlled is provided.
Technical scheme comprises case lid and is used to place the casing of lithium battery, and said casing one side has ventilating opening, and opposite side is equipped with ventilating fan.
Temperature sensor also is housed in the said casing, and the output of said temperature sensor is connected with the input of control module, and the output of said control module is connected with ventilating fan.
Said ventilating opening is communicated with in air channel and driver's cabin.
In the said air channel filter is housed.
In the said air channel unidirectional valve is housed.
The big I of said battery case is according to the size and the reasonable quantity design of concrete lithium battery; Series connection forms batteries between battery, and said temperature sensor can be responded to the variations in temperature in the casing, when temperature is surpassed predetermined value; Then control module starts ventilating fan work; Can the air in the battery case be extracted out, simultaneously the air-conditioning wind in the driver's cabin introduced in the battery case by air channel, ventilating opening, keep in the battery case ventilating thereby make; Its temperature is controlled in the claimed range, avoids influence too high or too low for temperature, that ventilate and freely lithium battery is not caused.The utility model is simple in structure, esy to use, safe and reliable.
Description of drawings
Fig. 1 is the utility model structural representation.
Fig. 2 is the scheme of installation (no case lid state) of battery press strip.
Fig. 3 is the utility model scheme of installation.
Fig. 4 is ventilating fan control principle figure.
Wherein, 1-casing, 2-case lid, 3-temperature sensor, 4-ventilating fan, 5-ventilating opening, 6-air channel, 7-filter, 8-unidirectional valve, 9-driver's cabin, 10-battery press strip.
Embodiment
With reference to Fig. 1-Fig. 3, can place the polylith lithium battery in the casing 1, and compress with battery press strip 10,2 of casing 1 and case lids adopt nut and waterproof grommet to be connected and sealed, and said casing 1 one sides have ventilating opening 5, and opposite side is equipped with ventilating fan 4.Temperature sensor 3 (at least one) also is housed in the casing 1, and the output of said temperature sensor 3 is connected with the input of control module, and the output of said control module is connected with ventilating fan 4.Said ventilating opening 5 is communicated with in air channel 6 and driver's cabin 9.Filter 7 and unidirectional valve 8 are housed in the air channel 6.
With reference to Fig. 4; Temperature sensor 3 is monitored the variations in temperature in the casing 1 in real time, when temperature surpasses predetermined value, then starts ventilating fan 4; Air-conditioning wind in the driver's cabin 9 is evacuated in the casing 1 via air channel 6, ventilating opening 5; Air-conditioning wind passes via the slit between casing 1 and lithium battery, lithium battery and the battery, is extracted out by ventilating fan 4 at last, makes to reach the purpose of ventilating and keeping the suitable temperature scope in the casing 1; When temperature is being provided with in the scope in temperature sensor 3 detects casing 1, quit work through control module control ventilating fan 4.The air-conditioning wind of said extraction can be according to heating in the driver's cabin 9 or the wind decision of freezing, if for preventing that temperature is low excessively in the casing 1, extract the air-conditioning wind of heat out winter; Extract cold air-conditioning wind for preventing that temperature is too high in the casing 1 summer.The cleaning that filter 7 guarantees wind regime is set in the air channel 6, and when unidirectional valve 8 assurance vehicle ' were set, interior adverse current wind can not pour in down a chimney entering driver's cabin 9 in the case.
Claims (5)
